I need a complete engineering package for a compact, stainless-steel (SS316) system that transfers two high-pressure gases—oxygen and a second gas—from 4 L, 1 800-2 000 psi supply cylinders into a 5 L storage tank. The small tank will serve purely for storage. Filling must occur in a defined sequence: first oxygen to a set intermediate pressure, then the second gas until the vessel reaches roughly 1 000 psi total. Gas purging is the preferred method for every line before and after each fill so that no pressure or cross-contamination remains prior to disconnecting the storage tank. The layout has to stay very tight—short runs only—and all wetted parts are to be SS316. Control and safety monitoring will be handled through a PLC with an HMI. Plan on integrating: &b...
